System Requirements:

Users should be able to perform the following tasks:

T1: choose a country as a baseline so that they can compare the other countries to the baseline for a given metric. For example, users should be able to answer the question, “How do [the chosen baseline country] compare to the other countries in terms of unemployment”.

The visualization must include all the countries, not a subset of them. It is fine if the visualization shows higher-level country groups (e.g., by region) to make the display more organized, but there must be a unique visual mark for each country.

T2: change the metric used in T1 (e.g., from unemployment to GDP growth), and the visualization should update accordingly. You DO NOT need to include all the metrics. Including the following six metrics would be sufficient:

GDP ($ USD billions PPP), GDP per capita in $ (PPP), health expenditure % of GDP, health expenditure per person, Military Spending as % of GDP, unemployment

T3: for the metrics that have data spanning across multiple years, users should be able to perform the comparison task in T1 for each individual year and see the temporal trends. 

Implementation:

Make a Choropleth Map. You are encouraged to use D3.js for this assignment, although it is not a strict requirement. The only requirement is that the system must be interactive and support the three tasks described above.

 

 

 

Some ideas(But feel free to change it)

Choropleth Map:

 

?             This map will display each country with a color scale based on the chosen metric. This will enable users to compare countries easily.

?             Users can select a country as a baseline, and the visualization should update to show the difference between the baseline country and other countries.

?             Users can hover over a country to see specific metric values.

Line Chart:

?             This chart will show the temporal trends for the selected metric across multiple years.

?             Users can click on a country in the choropleth map to display its trend in the line chart.

?             The line chart should display the trends of the baseline country and the selected country side by side for easy comparison.

c. Dropdown Menu:

?             Users can select a metric from a dropdown menu, and both the choropleth map and line chart should update accordingly.

?            

 

In short

?             Create a choropleth map with a color scale based on the chosen metric.

?             Implement interactivity to select a baseline country and update the visualization.

?             Create a line chart to display temporal trends for the selected metric.

?             Link the choropleth map and line chart so that selecting a country updates the line chart.

?             Implement a dropdown menu to switch between different metrics.

?             Style the visualizations and interface using CSS.
